13 Claims. 1

The present invention relates to new and useful improvements inattachments for textile looms and more particularly to means forsubjecting the filling to a constant drag as it comes off the shuttle toprevent backlash which causes imperfect weaving commonly known as sidelines.

An important object of the invention is to provide a guide attached to apart of the loom adjacent the filling and a brush, or pad, of suitablematerial for holdin the filling against the guide to maintain thefilling in a taut condition.

A further object of the invention is to provide means for automaticallyraising and lowering the brush or pad in accordance with the movement ofthe shuttle box and to further construct the brush or pad for theengagement of the filling in the brush to raise and lower the fillingabove or below the line of filling from a previous shuttle.

Another object of the invention is to provide a filling guide which willnot interfere with the action of the weaver when driving his shuttleinto the shuttle box, or when throwing his shuttle through the shed ofthe warp.

A still furtherobject is to provide an attachment of this character ofsimple and practical construction, which may be easily mounted inposition on a loom without necessitating any changes or alterations inthe construction thereof and which, at the same time, is efficient andreliable in operation, relatively inexpensive to manufacture andotherwise well adapted for the purposes for Which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure l is a front elevational view;

Figure 2 is a top plan View with parts broken awayand shown in section;

Figures 3 and 4 are enlarged transverse sectional view takenrespectively on the lines 3-3 and l4 of Figure 1;

Figure 5 is a group perspective view of the several parts of the upperand lower brush holder; and

Figure 6 is a perspective view of a fur pad for use with the guide inplace of a brush.

Referring now to the drawings in detail wherein, for the purpose ofillustration, I have disclosed a preferred embodiment of the invention,the numeral 5 designates the usual casting of a loom on which a reed cap6 and race plate are supported. Shuttle boxes 8 and 9 are shownpositioned at each end of the race plate and which carry the shuttles l0positioned one above the other in the shuttle box for aligning with therace plate 1.

A shuttle guard l l is secured at each end of reed cap 3 and is formedat its lower portion with an arcuate shoe l2 positioned immediatelyabove the race plate 7.

A resilient filling guide I3 comprisin a strap metal plate is providedadjacent one end with a longitudinal slot It for securing in avertically adjusted position behind the reed cap 6 by a bolt and wingnut IS, the metal strap extending upwardly and over the top of the reedcap and downwardly in front thereof and with its lower end indicated at[6 bent inwardly and frictionally held in the arcuate shoe l2 of theshuttle guard. The front surface ll of the filling guide I3 ispositioned above the race plate I to form a guide for the weft thread orfillin 4 of the shuttle during its movement, and the filling is held inengagement with the vertical surface 11 of the filling guide is by anupper brush or bristle-like member 18 and lower brush or bristle-likemember IS.

The upper brush i8 is provided with a twisted wire core 29 which usuallyprovides a handle for the brush and which, in the present instance,provides a twisted Wire supporting arm which is bent angularly for theinsertion of its end in an opening 2| of a brush holding block 22. Thearm 20 of the brush is held in the opening 2| by a set screw 23 tosupport the brush 18 in a vertical position in front of filling guidel3,

The lower brush I9 includes a lower horizontal portion 24 and an uppervertical portion 25 which is held against one side of the upper brush I8in an overlapping relation with respect thereto by means of a twistedwire core 26 inserted upwardly in the bottom of the brush holding block22 and secured therein by a set screw 28. l

The block 22 is formed with a horizontal slot 29 for slidably andpivotally mounting the block on a smooth portion 30 of a screw 31threaded in an opening 32a adjacent one'end of a substantiallytriangular shaped arm 32 to hold the block 22 against the outer surfaceof the arm. A stem 33 projects from the inner surface of arm 32 adjacentits end opposite from screw 3|, the stem 33 being received in a bearing34 of a bracket 35 secured to reed cap 6 for rockably supporting the armthereon. The bracket 35 is secured to the reed cap by means of a bolt 36positioned in a boss 31 on the bracket and projecting outwardlytherefrom.

A plate 38 is secured at one end to the outer end of boss 3'1 by screwsor the like 39 passing through openings 38a in plate 38 and threadedinto openings are in boss 31, and the other end of the plate is formedwith upper and lower stops fill and 4| positioned respectively above andbec low block 22. The block 22 is held against the end of plate 38between stops it and ll by means of a coil spring 42 connected at oneend to a pin 43 carried by plate 88 and connected at its other end to apin ill carried by block '22.

A screw 55 is also carried by plate 38 with its inner end abutting arm32 to prevent end play of stem 33 in bushing 34, the screw 45 beingadjusted relative to arm 32 by means of a nut it.

A wire arm G? has one end secured in an opening it at the free end or"arm sfi by means of aset screw it, the wire arm 4'! having its other endextended downwardly and formed with a foot iii loosely resting on thetop of shuttle box 3. One of the filling guide attachments is placedat'each-end of the reed-cap 6 for use with each shuttle box-i3 ande,theattachments being suitably constructed to form a right and a left forpositioning respectively at the right and left of *the loom, eachattachment functioning in a similar manner.

The brushes l8 and I9 are free at their lower ends whereby the weftthread=or filling i -may be easily placed upwardly in position behindthe br-ushesor removed therefrom, and as the shuttlesare-moved alongrace plate '1, the weft or filling passes between the guide it andbrushes l-B and iii, the brushes holding the filling taut to preventslack therein and thus avoid side lines or similar defects in the weave.

As the shuttle box 3 or 9 is raised'or lowered, the arm 47 is likewiseraised or lowered and transmits this motion to the pivoted arm 32 andblock 22 which carries brushes #8 and 9,1116 filling being engaged inthe bristles of the brush whereby one line of filling is kept out of thecourse of the next line from a-succeedingshuttle.

The upper and lower stops Gil and M limit the movement of block 2 2 andthe block sli es on pin 3b carried by pivotedarm 32 and is heldperpendicularly against the end of plate 38 by spring 42 to maintain thebrushes in a perpendicular position against guide -32 during raising andlowering movement to avoid twisting of the filling engaged by thebrushes.

If desired, a -liur or other suitable pador tufted member 56 having afilling engaging nap or tufted surface 51 and held taut in a wire frame52 may be interchangeably attached to block 22 in place of the brushes.

The upper brush 1% is needed at all times and lower brush [9 isnecessary when more than two shuttles are -in use. Both brushes are heldin a perpendicular position by spring 42 holding the block 22 againsttheend of plate 38, except as aiiected by the movement of the weft(filling) which, in the event of a backlash might cause a rotation ofblock 22 swinging the lower horizontal end 24 of lower brush l9 upwardlyinto a perpendicular position to at all times provide a perpendicularbrush for the weft. The use of both brushes eliminates the usual delayin changing the loom over from two to four shuttles and enablescontinuous and uninterrupted operation with two or more shuttles.

The brushes may be adjusted relative to guide plate 13 as required withrespect'to fine :or coarse filling being used to the point necessary toengage the filling andapply the necessary drag.
